To all my fellow Jackie disciples who have been touting her prowess lately: good news....the new Jackie Warner video will be available in November.
I may even pre-order, I'm such a dork.
I have also been doing lots of Jillian Michaels and Bob Harper of The Biggest Loser, as well as some of the exercisetv in-house trainers.
All the workouts I do use a circuit system of a few minutes of weights and then a minute or so of cardio, with the intention of burning out muscles to almost complete fatigue. Jackie likes to focus on single muscle groups more, she feels that the mind-body connection leads to better concentration, performance and form. The Biggest Loser trainers do more multi-muscle-group exercises, which they say produce maximum calorie burn. So they do various types of squats combined with arm weight exercises. The Jillian Shred video has a method of 3-2-1 which is circuits of 3 minutes of weights, 2 minutes of cardio and 1 minute of core. Keeps things changing for sure.
Personally I like both the combined idea or the singular muscle method, and switch them out based on mood. Generally if I run I do one Jackie routine and if I don't run I do a more comprehensive-type exercise.
All these videos are kind of focused on becoming strong and building a healthy body, but more than that the trainers seem unabashedly focused on creating a body that looks cut. It's so California and so strange, but it works like a charm!
